... restrictions. The approach is developed into a more realistic 2D coupled temperature–displacement model using commercial finite element analysis (FEA) software ( abaqus ) that utilizes the contact pressure, real contact area, and the ITL equivalent thermal conductance to estimate the effective thermal...

...Hee Joon Lee; Dong Yao Liu; Y. Alyousef; Shi-chune Yao Existing databases and correlations in literature on the microchannel pressure drop and heat transfer are reviewed in this paper. From this review, it is found that none of the existing correlations can cover the wide ranges of working fluids...

...André Burdet; Reza S. Abhari The pulsation of film cooling jets in turbines is driven by the near hole pressure fluctuation caused by the deterministic interaction of stator/rotor blade rows. Jet pulsation is characterized by the coolant near hole reduced frequency Ω c and the pulsation amplitude...

...S. N. Rogak; D. Faraji The constant pressure heat capacity and forced convection heat transfer coefficient of water/oxygen mixtures were measured in a horizontal, smooth, electrically-heated tube. For the supercritical pressure (25 MPa) considered, flow rates (0.76–2.04 kg/min), heat fluxes (21–290...

...Y. Feng; J. Seyed-Yagoobi The mechanism of heat transfer enhancement and pressure drop penalty in the presence of a radial electric field for the two-phase (liquid/vapor) annular flow is presented. The turbulence spectral theory shows that the radial electric field fluctuation changes the turbulent...

...Li Yong and; K. Sumathy Quasi-local absorption heat transfer coefficients and pressure drop inside a horizontal tube absorber have been investigated experimentally, with R-22/DMA as the working pair. The absorber is a counterflow coaxial tube-in-tube heat-exchanger with the working fluid flowing...

.... The axial variation of the unsteady component of velocity is compared to the local heat transfer, shear stress and pressure gradient. The results suggest that intermittently grooved passages may offer even higher heat transfer for a given pumping power than the levels observed in fully grooved passages...
